Select one: O The events Regift and Female are dependent because P(Regift) = P(Regift|Female). O The events Regift and Female are independent because P(Regift) = P(Regift| Female). %3! O The events Regift and Female are dependent because P(Regift) P(Regift|Female). The events Regift and Female are independent because P(Regift) * P(Regift|Female).

A coffee shop claims that it takes 115 seconds, on average, to serve their customers coffeethrough the drive-thru. Lucy, a statistics student, decides to test this claim. She randomlyselects 15 orders and records the wait time it took for the customer to receive their coffee.Here are the times (in seconds). 85 122 135 100 153153 116 99 65 130175 113 188 142 134(a) Why is it important that Lucy selects a random sample of orders? (b) Lucy wants to make a confidence interval to estimate the true mean wait time. Explainthoroughly why Lucy has or has not satisfied the “normal” condition for constructing aconfidence interval. (c) The 95% confidence interval for the true mean wait time is (109.1, 145.6) seconds. Does theinterval provide convincing evidence that the coffee shop is lying about their claim? Explain.
3595 You're a sociologist studying whether grocery prices are different in the inner cities than they are in the suburbs. To investigate this, you pick a random set of items (a basket of goods), and then send shoppers to buy these items at an inner city (IC) grocery, and also at a suburban (SU) grocery. You pick 35 different baskets of goods, so your secret shoppers buy 35 baskets, once at the inner city store, and once at a suburban store. Prices could be higher in the inner city because of discrimination, or they could be higher in the suburbs because of the greater disposable income. Use Excel to test the research hypothesis that inner city prices are different than the suburb's prices. The null hypothesis is that inner city prices are equal to suburban prices. You test at the alpha = 0.05 significance level. What do you conclude? Are prices the same? Who has higher prices? Group of answer choices You reject the null hypothesis; prices are different. Grocery prices are higher in…
